Default DMZ Server
The default DMZ server feature is helpful when you use some online games and
videoconferencing applications that are incompatible with Network Address Translation
(NAT). The router is programmed to recognize some of these applications and to function
correctly with them, but other applications exist that might not function well. In some cases,
one local computer can run the application correctly if that computer’s IP address is entered
as the default DMZ server.
WARNING:
DMZ servers pose a security risk. A computer designated as the
default DMZ server loses much of the protection of the firewall and
is exposed to exploits from the Internet. If compromised, the DMZ
server computer can be used to attack other computers on your
network.
To set up a default DMZ server:
1.
Log in to the router.

Change the MTU Size
The maximum transmission unit (MTU) is the largest data packet a network device transmits.
When one network device communicates across the Internet with another, the data packets
travel through many devices along the way. If any device in the data path has a lower MTU
setting than the other devices, the data packets must be split or fragmented to accommodate
the device with the smallest MTU.
The best MTU setting for NETGEAR equipment is often just the default value, and changing
the value might fix one problem but cause another.
WARNING:
An incorrect MTU setting can cause Internet communication
problems such as the inability to access certain websites, frames
within websites, secure login pages, or FTP or POP servers.
